Intramolecular carboxylic group-assisted cleavage of N-(2-hydroxyphenyl)-phthalamic acid (7) and N-(2-methoxyphenyl)-phthalamic acid (8): Absence of intramolecular general acid catalysis due to 2-OH in 7
The values of pseudo first-order rate constants (k(obs)) for the cleavage of N-(2-hydroxyphenyl)phthalamic acid (7), obtained at 4.9 x 10(-2) M HCl, 35 degrees C, and within CH(3)CN content range 2-80% (v/v) in mixed aqueous solvent are smaller than k(obs) for the cleavage of N-(2-methoxyphenyl)phth...
